What is one effect of virtualization on storage management?

One effect of virtualization on storage management is that it creates virtual instances and storage pools. Virtualization allows physical storage resources to be abstracted, enabling the formation of multiple virtual storage instances from a single physical entity. This capability facilitates efficient management and allocation of storage resources, allowing for dynamic reallocation based on changing workloads and demands. By creating storage pools, organizations can optimize usage, improve performance, and simplify provisioning, making it easier to manage and scale storage environments.

This contrasts with the other effects mentioned in the distractors. For example, virtualization does not limit the use of physical resources; rather, it enhances their utilization by pooling and abstracting them. Additionally, while hardware replacements may become easier due to the abstraction layer, this is not the primary focus of virtualization's impact on storage management. Lastly, virtualization is designed to improve data accessibility rather than decrease it, as it enables users and applications to access data through virtual resources more flexibly and efficiently.
